Kaschemme has finally released his CM10.1 V1 build for the K1.
A very hard work !
Congratulations and thank you very much for that nice job published on android-hilfe.de.
This is the first release V1.

link to the original post on android-hilfe :
www.android-hilfe.de/lenovo-ideapad-k1-f...-3g.html#post6056367

Caution :
By default there is no provision to reboot in recovery from the shutdown menu.
See two posts below to find how to enable the missing options after the first boot.

You should 1st download the Gapps (Google Apps) from Google and store the file in your sdcard and install the apps just after having flashed the new image.
This will insure that you will have access to the Play Store after booting JB 4.2.2 without the need to reboot in recovery.
Kaschemme insists to install only this Gapps non neon version :
www.dropbox.com/s/724l3cc8bos87r4/gapps-...n-tonyp-keyboard.zip
Google does no longer support non neon systems, so a kind folk has replaced the libraries in that package, making it compatible with non neon devices.

I've patched the image for the Medion Lifetab P9516.
I've also replaced the original boot animation by the Lifetab animation.

It isn't useless to remind :
DISCLAIMER 1*
This site bloggers and YLG80 takes no responsibility for any fault or damage caused
by any procedures within this guide. No warranties of any kind are given.
If you don't know what is nvflash, adb, root or cwm, chances are that you don't need to do
what is described below.
In short, if you hard brick your device, you are on your own.

*CAUTION*
Do never interrupt the upgrade while its running.
This is especially important when you see start updating EBT and BCT on the tablet screen.(blob flashing)


Now that you know ... here is the CWM ZIP file download link :

VERSION V1x of 20130710

Known bugs :
Light Sensor
USB Stick[fixed]
Headset detection
Automatic Spelling checker

[NEW VERSION NIGHTLY BUILD of 20130711]
www.dropbox.com/s/vqthyjxpa2rlunb/medion...20130711_NIGHTLY.zip

CWM Recovery updater
Due to the multi user configuration the old CWM recovery does no longer work correctly.
The backup creates multiple directories and the MD5 checksum is incorrect.
Please use this script from Mickey to update the CWM recovery in your Medion P9516 tablet using nvflash.
THIS IS AN NVFLASH SCRIPT.
Simply decompress the zip start the script from directory.

CWM 6.0.3.2 recovery updater script : https://www.dropbox.com/s/5vli4j66v9ho5av/cwm-6032.zip


Please report any problem, as I believe Kaschemme is sometimes coming here.

Enjoy.

Funny !
Here is how to get the other CM10.1 reboot options:
You need to be elevated to the developer status

Open Settings and touch "About tablet", last option in the left menu.
Then on the right side, scroll down to the build information.(very lat information in the list)
Tap several times on the build information.
You will see a message saying that you are x taps from the developer status.
Continue to tap.

Once you have been granted to the Developer status, you will have access to the Developer menu on the left side.
Cool!

Wow... tested for some minutes: Everything is very nice!
Lots of features I was waiting for!
For the bugs: I hope, kaschemme can fix them, but I don't need USBsticks badly We have the SD-slot...
Have to try, if my mouse or gamepad work over USB, but its to late now.

Thank you kaschemme, YGL80 and Ameisent├Ątowierer and everybody involved - Vielen Dank f├╝r die viele Arbeit!

Re: CM10.1 JB 4.2.2 from Kaschemme (3G ) for LT P9516 8 years, 2 months ago #2039

Looks like superuser is built-into CM10.1 (see attachment).

Worked for me out-of-the-box.
Even for Titanium backup.

Also mounting /system read/write works:
 
root@android:/ # mount | grep -i system
/dev/block/mmcblk0p3 /system ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
root@android:/ # mount -o rw,remount /system
root@android:/ # mount | grep -i system
/dev/block/mmcblk0p3 /system ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
root@android:/ #
 


adb didn't work:
I had to configure Settings->Storage->Connection to make adb working...


But my virtual keyboard is crashing after typing 2 characters....
BTW: did you try gesture-typing? a really great feature!
(had to use non-neon-gapps + factory-reset to make it work)

Hello,
Yes Superuser is built in, but for some reasons certain apps could not get su permissions.
I will test it again removing Koush SuperUser App.
Before installing Koush SuperUser I could not issue the su command when in terminal mode.

Gesture keyboard is working OK. Great feature, but I should disable the auto spelling, as it starts each command with an uppercase
character when in terminal mode !

adb : I had no problem to start an adb connection right after the image installation.

@ Mickey
Why does it display root@android/# in your terminal while here I get u0_a41@android/ # ?
You are right, /system is in rw mode, but the USB Mass Storage OTG app cannot mount the key. (readonly error)
I've tried to mount in the existing /mnt/usbdisk/ or in a newly created directory to no avail.

Did you try to install a zip from sdcard0 in CWM. It looks like the mount points are somewhat exotic.
Why these symlinked directories /0 and /legacy under /storage/emulated ?

Other than that, the build looks quite stable !

Hmmm I probably discovered a bug:
When connected to a bluetoothspeaker video and musicplayback doesnt work. Video starts to lag without sound- music does not play, when connected.
Worked in CM10 builds. Probably a kernel problem? Or only on my LT? If anybody confirm it working, I will try a clean install...

Not probably. Confirmed.
You are absolutely right.
I've taken that opportunity to test the tablet with my car bluetooth system.
I had even to reboot my tablet afterwards. The adb server remained offline !
Thats a bug to be reported to Kaschemme.

@Mickey,
Now I've lost adb as well ! Always offline.
After the first boot, I've been able to upload the Gapps with no problem.
Even switching the options in Storage does not help.
Killing the restarting adb server does not help either.

My mistake !
Typing error in USB VID (adb) in init.usb.rc
I'm correcting the errors and refreshing the image file. Takes a moment ...
People with the adb problem will have to make a no loss update with the new image.
Sorry.
Yves
BTW I'm not sure if it will affect Linux users ...
Also, despite of a correct adb driver, it does not resolve my adb offline issue

adb problem fixed !

The problem is due to a new encryption mode with JB 4.2.2
You just need to update your adb executable in your PC.
The new adb client from the last SDK version can be found here:
http://appinventor.mit.edu/download/adb.html

Once launched you will receive a message like this on your PC display: Server outdated. Killing server.
Check your tablet screen and you will see a popup window with the encryption key.
Acknowledge the use of that key with your PC, and you will be ready to go !

Linux is not affected by wrong USB-IDs

Keyboard p...
[switching to n4]
problem only occurs in browsers in input fields.
Happens with default browser & chrome.
Horrible!

Mediaserver is eating my cpu & battery.

Usb-stick isn't even detected. That's why you can't mount it.

My post shows root@android, because I used adb shell.

I think that cwm doesn't know how to handle multiple users, that's why you see /0 /legacy.
Create another user and you'll see another subdir.
Try
pm list users
in a shell to see a list of users.
Unfortunately it seems, that a user can't logout himself...

Kernel still is 2.6.39, with wlan bug.

There are problems, but it's promising!

Thx kaschemme

New release V1x from Kaschemme.
Thanks for that quick update with several fixes :
- usb storage fixed
- add new media codec
- media settings has been optimized (720p)

See first post for the Medion LifeTab P9516 flavour download.

This is a no loss update.
No need to wipe cache.
USB host tested OK.

Thanks for the update.
Bluetooth is still not working.
Neither the wireless speaker nor the BT keyboard.
I can't see any posts in kaschemmes threads on androidhilfe and xda belonging to that problem.
Should I try to install the original version for Lenovo?
Another question:
@YGL80 why didn't you change the tablet name in build.prop is there a specific reason for?

@MaD.
Perhaps Kaschemme has not remarked your bug report, because you have edited a previous post to add your bug description.
Or perhaps he will only fix that in the new release CM10.1.1 .
He announced that this will be the last CM10.1 update.

The K1 image will not resolve that issue, as the hardware and the kernel are exactly the same, except for the build properties, USB VID/PID and boot animation.

Anyway, it's time to explain how to permanently convert your Lifetab into an Ideatab K1 so that you can use directly kaschemme updates.
In Kaschemme image updates, there is a K1 condition in the update script to prevent the update to run in non K1 machines.

To update your P9516 in a K1, go to the Google Playstore, grab and install BuildProp Editor
Launch BuildProp editor and scroll down to ro.product.device build property.
Modify that property from MD_LIFETAB_P9516 to K1 and save the new property.

Now you can use Kaschemme images for the Ideapad.
Except for the bootloader, you tablet will look like an Ideapad K1.
In case of warranty call, you can revert to the Medion config, doing exactly the opposite.

Yves


PS please note that Google (PlayStore) will give you a warning due to the tablet change.

Thanks to Lars (magiclb) to warn me about the CWM recovery issue and update.(see first post for the recovery updater)

Kaschemme has announced that the current CM10.1 image will be that last update.
He is working on CM10.1.1
He will perhaps include the recovery update in his next release, if you don't dare to use the updater script right now..

About the recovery problem, you can find the explanation in a rather condensed and difficult to read post here:
forum.xda-developers.com/showpost.php?p=...288&postcount=48

Yves

Re: CM10.1 JB 4.2.2 from Kaschemme (3G ) for LT P9516 8 years, 2 months ago #2052

Hi Yves,

don't forget CWM.

The recovery(-image) also contains ro.product.device.
This is checked in the installation of the image.
You have to change this too, or grab krook's image, extract boot.img and write it to the SOS-partition...

OK, I've uploaded the CWM recovery 6.0.1.1 to 6.0.3.2 updater (for Medion).
See first post.
I've used Mickey's complete package rather that Kaschemme method.
So it's an nvflash update.

Bluetooth issue with CM10.1

I've tested that functionality with several players, and it looks to me that it's a codec problem.
If you install ArcMedia, it plays perfectly video with no lagging at all when BT is connected ... but still no sound .
In fact I cannot stream audio via bluetooth at all.(mp3 files)

Are you able to stream audio only (mp3) via BT ?

About your tablet name question:
Do you mean why not changing the P9516 name into K1 once for all?
If I remember, we did not change the tablet name in order not to loose the Medion pre-installed applications (i.e DocstoGo)

Mickey, what do you think about that? That's a very good question !

@YLG80
I could not play any audio file via BT- D didnot test every file...
For the name: My P9516 is identified as Lenovo K1, thats, why I asked. Docstogo is no reason for me as I purchased the app for my SGS1 so long ago.
For other apps I could not install I renamed the tablet to Samsung I9100 some roms ago, so I was able to install more apps at Gplay
So I had a i9100 tablet in playstore...! Later I left the name locations empty in build.prop and also was able to install everything.

What do I have to change for USB Vid?
